There's quite a bit of bipolar running in my family. I definitely have some tendencies in that direction, which have thankfully never fully erupted. It's been a big factor in my becoming FI. I'm still working but have very intentionally scaled back ambitions. I currently have a very low stress job and resist any temptations I occasionally get to move into something that might be a better "Opportunity", but would likely lead to more stress. The low stress of my job is lowered even further by knowing that I could quit anytime, which allows me to pick and choose what I want to work on and not be pressured into anything.
It sounds like you're working to be on a good path, but are pretty stressed out by the process of that, which is understandable.
My only advice, which works for me, but obviously everyone is different, is to allow yourself to guilt-free work on your own peace and happiness. It's so easy for me to go down the slippery slope of pushing myself to get stuff done, feeling bad about taking me time when my wife is taking care of our son, or feeling like I need to be doing stuff to keep up my end of the bargain (work, relationships, whatever). It took me a long time to fully accept that Priority #1 for me always has to be doing whatever I need to keep my head right. If I don't manage that, nothing else is doable.
Good luck with your progress!
